Description of Lenox Tools 1225618DGHS Diamond 8 Inch: Unparalleled Precision and Performance
LENOX Diamond hole saw has a brazed diamond edge for more holes in tile and stone. Diamond-tip hole saw has a durable, robust design for greater versatility in tough applications. Diamond-tipped hole saw cuts holes in less time than carbide-grit or carbide-tipped hole saws. Round holes make removing plugs faster and easier. Uses a 1L, 4L or 5L standard arbor or a 5L SNAP-BACK arbor.
Will drill approximately 20-30 holes in 1/4" flat glass before it wears out. This is pretty good compared to other glass drill bits in this price range (I drill thousands of holes in glass aquariums).
Didn't want to spend money on a disposable or dual use item but I tried a cheaper product and it doesn't work for squats I got it in the hopes Bought it working and wasn't disappointed. I've actually used it a few times on all the tile work I've done and I'm very happy with it.
Bought to drill holes in brick to get electricity outside. Works amazing! After drilling the brick, I drilled through the tiles for the installation and cut them like butter! I highly recommend the Lenox brand if you need a diamond grit hole saw! Just remember to slow down, get water on it and NOT BE A HAMMER! It's practically the same type of bit that we use on the Milwaukee core drill!
